Amazon's 'GameCircle' adds achievements and more to Kindle Fire games

In an effort to woo developers to its Android-powered Kindle Fire tablet, Amazon has announced GameCircle. The series of new APIs allow developers to integrate a number of new features into games designed for the Fire.

GameCircle adds an achievement system, leaderboards and sync. Sync may be the most interesting feature, as it allows players to save their game progress in the cloud, so that they can pick up a game session after switching devices or even after restoring a deleted game – a valid concern considering the Fire's roughly 6GB of usable space.

The video above explains GameCircle in more detail. Developers interested in integrating GameCircle into their games can sign up for an invitation right here.
